14 Calculating the bending forces There are two different variants to the bending process: Air bending Coining The press force (F) in coining is 3 to 8 times higher than in air bending. The necessary press force (F) results from the die opening width (V) and the material thickness (t). The die opening width (V) should be 8 to 12 times the material thickness. For bevellings using this die opening width (V), both the shortest arm (b) and its angle (α) must be taken into consideration. If a smaller die opening width (V) is selected, the internal radius (r i ) obtained is smaller. Air bending Coining t Use the press force table and the appropriate equations to determine the reference values. b S Press force table (press force in t/m r i, b, V, t in mm) Required press force for 90 air bending material 450 N/mm 2 Internal radius r i Minimum edge b t = material thickness F = press force V = die opening width b = minimum edge S = shortest arm length r i = internal radius α = angle ri V t Die opening width V Material thickness t required press force F in t/m xample: Material thickness t = 4.0 mm optimum die opening width V = 32.0 mm minimum edge b = 20.0 mm shortest arm length S = 24.0 mm internal radius r i = 5.3 mm required press force F = 34.0 t/m Determining the die width opening V in mm: Material thickness t in mm and above Die opening width V 8 x t 10 x t 12 x t Determining the shortest arm length S in mm: S = b + t Tensile strengths: Aluminium R m = N/mm 2 Steel R m = N/mm 2 High-grade steel R m = N/mm 2
